Hi folks,Sorry to take so long to reply but I was on vacation.
I measured the belt path with out the A/C and cameout with 50 or 51. I picked up both belts to try.
The 51 was a good fit. I installed it and left for vacation.
I've put on 2000+ Kms during my trip and had no problem with the belt at all.
Now if someone could only tell me how to free a canoe that's wrapped around a rock in a rapid out in the wilderness.
(The helicopter rescue was a blast!!)
